Wales and West Utilities 


HWM has been working with Wales and West Utilities to help the energy provider monitor and report gas consumption and pressure.

Wales and West operates the gas network across Wales and the South West England regions of the United Kingdom. They are required to supply gas to Short Term Operational Reserve (STOR) power stations during periods of peak demand.

Electricity Generation is achieved by gas powered generators housed at these sites. An example site houses ten standby gas engines and associated plant which will generate a total of 16,000kW. The standby power generators are usually required to operate between 07:00 and 21:00 hours, although most are likely to operate during peak load hours only.

To safeguard the network, Wales and West have Network Exit Agreements with these sites which have maximum gas ramp up/down and usage rates detailed.

Wales and West's main objectives were having the ability to monitor Gas flow to ensure their customers were compliant within agreed limits and to also help safeguard supply to the local gas network. This is where HWM introduced Wales and West Utilities to their innovative ATEX approved Intelligens GNS logger.

The GNS logger has been specifically developed to measure network pressures at gas governor stations but most importantly for Wales and West Utilities, the Intelligens logger is also able to monitor flow from gas meters.

This is achieved by using accumulative pulse counting technology to calculate index readings against a known volume. The Intelligens logger can be mounted in close proximity to either a commercial or domestic gas metre, or on any other utility meter that has a pulsed output. The internal pressure sensor can be paired with an additional (or multiple) external pressure sensors, allowing for accurate measurements across a broad range of pressure combinations.

This innovative technology ensures that specified pressures and volumes can be monitored, helping to ensure that network supply is not compromised.
